Przerzeczyn Wastewater Treatment Plant, Podlesie | Closed Secondary Facility in Lower Silesia

Przerzeczyn wastewater treatment plant is located in Podlesie, a village in the gmina of Niemcza, within the dzierżoniowski district of the Lower Silesian Voivodeship in southwestern Poland. The plant was designed to treat wastewater from the local population, with a capacity of 2,830 cubic meters per day, and provided secondary treatment before its closure. As a Polish wastewater facility, it operated under the national regulations implementing the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this scale, secondary treatment is the standard requirement, ensuring the reduction of organic matter and suspended solids before discharge. The plant's closure may reflect infrastructure upgrades or consolidation in the region. The treated effluent from the plant would have discharged into local watercourses that eventually drain into the Oder River basin, which flows northward to the Baltic Sea. The Lower Silesian region is characterized by agricultural and rural landscapes, and proper wastewater treatment is essential to protect local streams and groundwater from nutrient pollution.

The plant's receiving waters are part of the Oder River basin, which ultimately drains into the Baltic Sea. The region's aquatic ecosystems support diverse species, and effective wastewater treatment helps prevent eutrophication in downstream water bodies. The area is also near the Sudetes mountain range, where water quality is critical for both ecological health and human use.
